I use a dynamic microsimulation model to analyse the distributional effects of an expansion of education in Côte d'Ivoire in the medium and long term (1998-2015). The simulations are performed in order to replicate several policies in force or subject to debate in this country. Various hypotheses concerning the evolution of returns to education and labour demand are tested. The direct effects between education and income as well as the different transmission channels, such as occupational choices, fertility, and household composition, are analysed. The effects of the expansion of education on the growth of household incomes, their distribution and poverty depend very crucially on the hypothesis made on the evolution of returns to education and labour demand. If returns to education remain constant and the labour market segmented, the effects will be very modest
